Air-advanced Work Supports have a plunger that is normally retracted for clear loading. Applying air pressure gently advances the plunger to the work piece with light, adjustable force. Applying fluid pressure locks the plunger securely.

BESONDERHEITEN: Work Supports automatically adjust to the proper height for supporting a workpiece, then lock securely to become fixed rests. Support plunger is held by a precision sliding-fit pressure sleeve that provides incredible accuracy and repeatability. Air-advanced Work Supports allow fine-tuning contact force using a Fine Air Pressure Regulator, and provide separate control of plunger advance. The threaded-body version shown here is amazingly compact. Manifold mounting capability allows space-saving lowheight installation. Hardened contact bolt furnished.
GRÖßEN: Available in one size, with metric threads — see Dimensions page for part number. Load capacity at 7500 psi:
ABSTÜTZFUNKTION: Plunger is normally retracted for clear workpiece loading and unloading. Applying air pressure gently advances the plunger to the workpiece, where it contacts with light force (a Fine Air Pressure Regulator, Air Extractor Dryer, and Air Clamping Valve are required for air control). Fine-tune contact force using the air regulator. When fluid pressure is applied, the precision sleeve grips the plunger, locking it securely. The plunger retracts again when fluid pressure and air pressure are released. These Work Supports can also be used as "Air Extended" supports by leaving air pressure constantly on.
GENAUIGKEIT: Height repeatability within +/-.0002". Such excellent repeatability is possible because of two design features: 1) the sliding-fit pressure sleeve holds the plunger absolutely vertical even while unlocked, avoiding any inaccuracy due to locking a tilted plunger, and 2) locking force is entirely radial, so the plunger remains absolutely stationary during the locking process. Elastic deflection of the plunger is only .00012" per 100 lbs machining load.
DESIGN-HINWEISE: The support plunger must always be protected against penetration of contaminants by a contact bolt (furnished). When supporting underneath a clamp, use a Sequence Valve to delay clamping until the Work Support has reached sufficient load capacity to resist the clamping force. Support load capacity should be at least 2 times clamping force at all times, to resist not only static clamping force, but also dynamic forces due to clamping-arm momentum and machining forces.
MONTAGE: For manifold mounting, install support directly into a flat-bottom tapped hole in the fixture – see Dimensions page for hole preparation instructions. Support can also be installed in an optional mounting block, which is fastened using socket-head cap screws. In all cases, hydraulic sealing is accomplished by a Sealing Washer (furnished) placed directly underneath the support. Tighten to the recommended seating torque of 74 ft-lbs.
HYDRAULIK-ANSCHLUSS: For manifold mounting, fluid passages must be drilled as shown in the drawings. Do not use NPT fittings.
